PRECAUTIONS TO BE TAKEN BEFORE STARTING THE ENGINE 2.3 PRECAUTIONS TO BE TAKEN BEFORE STARTING THE ENGI- NE 2.3.1 SAFETY ON THE WORK SITE Before starting the engine, thoroughly check the area for any unusual condition of the ground due to which work may be dan- gerous. Check the conditions of the ground at the work site and before starting the engine define the work plan and the best and safest operating procedure. Make the ground surface as level as possible before carrying out any operation. In case of work on the road, protect pedestrians and cars by de- signating a person for work site traffic duty and install fences around the work site.
RWA21920 If water lines, gas lines, and telephone or high-voltage electrical lines are located under the work site, contact the relevant utility company in order to find out their exact positions or to make them ineffective until the end of the operations. Be careful not to sever or damage any of these lines. Check the depth and flow of water before operating in water or on river banks. 2.3.2 FIRE PREVENTION Carefully remove all wood chips, rubbish, paper and other flam- mable materials that may have accumulated inside the engine compartment, since they can cause fires. Check the fuel and hydraulic system pipes for leaks and if ne- cessary repair them.
Wipe up any leakage of oil, fuel or other flammable fluids. Make sure that fire extinguishers are available for use in the work area. RWA01040 2.3.3 PRECAUTIONS TO BE TAKEN FOR THE OPERATOR’S CAB Do not keep objects or tools in the operator’s cab. They may hinder the operation of the controls and cause se- rious accidents. Keep the cab floor and the controls (pedals and levers) clean, by removing any trace of oil and grease and, as far as the floor is concerned, remove any excess dirt (earth, stones, etc.). Check the safety belt and change it if it is broken or damaged. Replace any component only with homologated parts supplied by Komatsu Utility or its Dealers. 33
